Social entrepreneurial intention among university students in China

The issues of employment, social inequality, and resource scarcity can be effectively addressed through social entrepreneurship, contributing to the growing research interest on the formation of social entrepreneurial intention. Using the theory of planned behaviour, the current study examined the influence of selected key factors on social entrepreneurial intention among university students. Based on the cross-sectional quantitative research design, online survey was conducted, which involved 684 students and graduates from five universities in Southern China. The obtained results demonstrated the significant and positive influence of perceived values on sustainability, opportunity recognition competency, attitude towards entrepreneurship, subjective norms, and perceived behavioural control on social entrepreneurial intention. Additionally, attitude towards entrepreneurship partially mediated the relationships of risk-taking propensity, self-efficacy, and need for achievement on social entrepreneurial intention. The multi-group analysis results also showed that need for achievement and social entrepreneurial intention differed significantly between genders, which provides new ideas for future investigations into the impact of gender on social entrepreneurial intentions. Based on the findings of this study, it is crucial that university students are exposed to relevant courses or training to develop social entrepreneurship competencies and promote sustainable values. The findings of this study will provide policymakers with relevant policy guidelines and more effective theoretical support to achieve the goal of promoting social entrepreneurship among university students in a more resource-efficient and effective manner.


Social entrepreneurship in China
China's nonprofit sector is heavily influenced by the state, which distinguishes it from most economies because of its deep political embeddedness 36 .The endeavor to transition to a market economy creates a unique environment for social entrepreneurs 37 .China has witnessed significant growth in social entrepreneurship over the past decade, recognizing it as an innovative approach to address economic and societal challenges in developing countries like China 38 .
Although there is currently no official certification channel for social enterprises in China, numerous certified social organizations exist 39 .These include rural cooperatives, rural enterprises, for-profit entrepreneurs participating in the Guangcai/Glorious Program, and nonprofit organizations, all of which exhibit characteristics akin to social enterprises 40 .However, the insufficiency of government procurement and subsidies as sustainable funding sources for many social organizations' daily operations has led to the adoption of simultaneous registration of commercial enterprises as a viable solution 39 .In this context, Farhoud et al. 41 have also proposed that social enterprises should encompass entities within the non-profit sector, the for-profit sector with a social mission, and hybrid organizations.
According to the Global Entrepreneurship Monitor's 2023-2024 Global Report (GEM 2024), over 60% of startups in China prioritize their societal and environmental impact, thus highlighting Chinese startups' significant concern for addressing social issues.However, despite the rapid development trend of social entrepreneurship, there are few studies specifically focused on social entrepreneurship within the Chinese context 42 .Most scholars concentrate on aspects such as the development of social entrepreneurship, economic benefits associated with social enterprises, and the role of entrepreneurial education in fostering social entrepreneurship [43][44][45][46] .A limited number of studies have also examined social entrepreneurial intention (SEI), such as Yang et al. 38 , who investigated the impact of values, beliefs, and norms on the social entrepreneurial intentions of employed individuals using the Values-Beliefs-Norms model.Choi et al. 47 , utilizing data from senior college students at a www.nature.com/scientificreports/Sino-American university in China, explored changes in SEI across gender prior to and during the COVID-19 pandemic, as well as the influence of environmental and personal factors on SEI.However, there is significant potential for research to uncover the precursors of SEI.The study aims to explore Chinese university students' and graduates' perceived values on sustainability, opportunity recognition competency, attitude towards entrepreneurship, subjective norms, and perceived behavioural control on SEI based on TPB with an aim to enhance SEI research in China.

Theoretical foundation
TPB has been widely used as the underlying theoretical basis for studies on entrepreneurial behaviour 48 .According to TPB, intention predicts the actual behaviour and elucidates the extent of efforts one makes to execute a planned action 49 .Ajzen 48 suggests that in most cases, people's behaviour is not entirely voluntary, but rather under control.Such influences from oneself, society and perception lead people to develop a particular plan aFnd then form the intention to carry it out before implementing the action.TPB is commonly used as a framework to measure intention and behaviour across various contexts 17 .
According to TPB, attitude, subjective norms, and perceived behavioural control shape one's intention or in other words, one's tendency to perform a specific behaviour 50 .Nasar et al. 49 defined attitude as one's way of thinking, feeling, or opinion about a specific behaviour or an activity related to personal preferences, strengths, weaknesses.Meanwhile, Gorgievski et al. 24 defined subjective norms as one's perceptions of the social support or pressure received when one engages in a certain behaviour or activity.Perceived behavioural control refers to the cognitive evaluation of one's ability to execute a specific activity; in this case, this construct reflects one's awareness of the skills required for entrepreneurship 51 .
TPB was considered the underlying theoretical basis for the study of entrepreneurial behaviour.According to TPB, university students' attitudes towards entrepreneurship (ATE), subjective norms (SUN), and perceived behavioural control (PBC) can positively influence their entrepreneurial intentions 52 .Individuals who show an interest in entrepreneurship usually listen to the advice of those around them, and receiving feedback may influence their decision to accept entrepreneurial activities based on attitudes, SUN, and PBC 22 .One of the benefits of TPB is that its original structure can be altered to suit more precise research domains and improve the quality of acceptable results, making the TPB model attractive for SEI research 53 .In particular, the study examined the influence of perceived value on sustainability (PVS), opportunity recognition competency (ORG), ATE, SUN, and PBC on SEI.The addition of the variables PVS and ORG, which complement the TPB in this study, allows for a more detailed and varied approach to improving SEI in terms of sustainable values and personal capabilities.Furthermore, ATE was conceptualised into risk-taking proclivity, self-efficacy, and the need for achievement to be discussed in greater depth from a psychological standpoint.

Risk-taking propensity (RTP) and attitude towards entrepreneurship (ATE)
Risk-taking propensity describes one's willingness to take risks 54 .Entrepreneurs, especially of those without entrepreneurial experience or high education level, need to have significantly high risk tolerance 55 .Starting a new start-up with limited resources and unknown market potential comes with the risk of failure that may result in psychological risk and even health risk 56 .It has been found high risk-taking propensity among university student entrepreneurs 57 .University students who choose to be an entrepreneur, instead of securing a job with stable income, are already taking the risk 58 .Those who are not willing to take the risk due to the fear of failure are likely to overlook certain opportunities 59 .Risk-averse individuals are more likely to be resistant against entrepreneurship opportunities since they cannot afford the stress of failure, whereas individuals with risk-taking propensity tend to be more confident and better equipped to respond and make decisions to achieve entrepreneurial success 60 .Moreover, students' risk-taking motivation and behaviour were significantly and positively associated with their determination to undertake social entrepreneurship 61,62 .In view of the above, the following hypothesis was proposed for testing in the current study: H1 RTP positively influences ATE.

Self-efficacy (SEF) and attitude towards entrepreneurship (ATE)
Bandura 63 derived self-efficacy from the social cognitive theory and postulated its formation through mastery experience, social modelling, and social persuasion.According to Bandura 63 , self-efficacy determines the perceived self-enabling or self-diminishing manner and influences one's decision-making.Meanwhile, Udayanan 64 described self-efficacy as one's belief that he or she can successfully perform a task.Self-efficacy can also explain one's entrepreneurial attitude 65 .Individuals with self-efficacy are more likely to exhibit entrepreneurial potential 66 .Entrepreneurs with higher self-efficacy demonstrate higher confidence to succeed, whereas entrepreneurs with lower self-efficacy demonstrate lower confidence and take the next under the guidance of others 67 .Low entrepreneurial confidence potentially causes one to have poor commitment in entrepreneurship or even give up entirely.For example, as social issues are quite complex, if the self-efficacy of potential social entrepreneurs is too low, it may constitute a psychological barrier 68 .Increasing perceived self-efficacy serves as a crucial goal in entrepreneurship education for university students, enabling them to strengthen their beliefs in entrepreneurship and receive psychological and emotional support 69 .Individuals with higher perceived self-efficacy in entrepreneurship demonstrate more passion in entrepreneurship and positive attitude towards entrepreneurship 70 .Thus, the following hypothesis was proposed for testing in this study:

Need for achievement (NFA) and attitude towards entrepreneurship (ATE)
According to the achievement theory, the strength of need for achievement affects one's motivation and performance 71 .Yohana and Salsabila 72 defined need for achievement as the motivation to achieve and be successful in a set of legal relationships.The existing literature on entrepreneurship has identified need for achievement as a determinant of entrepreneurial success 73 .Several prior studies highlighted need for achievement as the most crucial predictor of entrepreneurial intention 74 .Being a social entrepreneur is inherently about the pursuit of economic benefits and the achievement of addressing social inequalities 75 .The greater the need for achievement, the more eager entrepreneurs are to take risks 76 .Furthermore, students whose achievement needs are highly satisfied feel better psychologically and are able to consciously learn and exercise the competencies needed to start and develop new social enterprises 77 .All these facts suggest that higher achievement needs inspire more positive attitudes towards entrepreneurship 65,78,79 , whether for social entrepreneurs or for entrepreneurs in general.In view of the above, the following hypothesis was formulated: H3 NFA positively influences ATE.

Perceived values on sustainability (PVS) and social entrepreneurial intention (SEI)
The concept of sustainability has recently gained significant attention, and its concept varies in different contexts.Jaramillo et al. 80 described values on sustainability as the principle of simultaneously enhancing one's competitive advantage and monetary or non-monetary benefits.From a business perspective, Faulkner and Badurdeen 81 defined sustainability as making rational economic decisions in the selection of production systems that can reduce adverse implications on the environment and consider the conservation of energy and natural resources.Meanwhile, Husgafvel 82 defined social sustainability as a standard social sustainable practice or performance related to the society, organisation, business, group, individual, product/service/process, or an activity (or activities).Thus, the current study viewed perceived values on sustainability as the principle related to sustainability practices with the emphasis on pro-environmental behaviour.
Values influence how individuals become what they favour or perceive and reflect how individuals view a certain subject or matter 83 .As consumers, perceived values effectively predict behavioural intention 84 .For instance, diners with perceived values on sustainability are generally more concerned about the environment and less likely to waste food 85 .When talking about social entrepreneurship, it is often associated with social responsibility and the creation of sustainable values 86 .Social entrepreneurs place substantial concern on sustainability 87 .They have a mindset of concern for social and environmental issues and are able to integrate sustainability values into their company's mission and work with other indicators related to entrepreneurial activities 88 .These studies suggest a potential positive correlation between sustainable values and SEI.Moreover, based on the perceived values on sustainability, individuals emphasise combining social, environmental, and economic values with the emphasis of creating social and environmental values, and these positive perceptions are positively related to the intention of starting a sustainable business 89 .In view of the above, although there was no evidence of the direct relationship between PVS and SEI, the following hypothesis was proposed for testing: H4 PVS positively influences SEI.

Opportunity recognition competency (ORG) and social entrepreneurial intention (SEI)
As one of the key concepts in entrepreneurship, opportunity recognition is a process of discovering and understanding a certain change and deciding whether to act on the change 90 .Opportunity recognition competency is a specific ability that involves identifying and developing ideas, which is a criterion to the process of recognising an opportunity 91 .Recognising business opportunities has long been recognised as a criterion to realising entrepreneurship 92 .Several prior studies demonstrated the positive influence of opportunity recognition competency on students' entrepreneurial intention 79,91 .However, the influence of opportunity recognition competency on social entrepreneurial intention has remained underexplored.
According to Trajano et al. 93 , the unmet social needs highlighted by community volunteers are identified as business opportunities, which then motivate the formation of social entrepreneurial intention.Social entrepreneurs also aim to meet unmet social needs by providing solutions and creating social value 31 .Basically, these volunteers and social entrepreneurs share similar attributes.Before they decide to meet social needs, they should first identify them 31 .It suggests that having the ability to identify social needs and turn them into useful business opportunities is necessary for those intending to engage in social entrepreneurship.Hoong et al. 94 shared similar view on the significance of opportunity recognition competency as a determinant that can enhance one's social entrepreneurial intention.It is also important to note that there are some differences between social entrepreneurs and general entrepreneurs in terms of identifying opportunities.Social entrepreneurs identify opportunities based on their observation of the social issues, while others may only consider these issues as threats to their business 95 .With that, the following hypothesis was proposed for testing: H5 ORG positively influences SEI.

Attitude towards entrepreneurship (ATE) and social entrepreneurial intention (SEI)
According to TPB, attitude towards a specific behaviour describes one's (favourable or unfavourable) evaluation of the results of the behaviour 48 .Attitude can also be viewed as the outcome of one's evaluation of whether www.nature.com/scientificreports/ a certain behaviour aligns with personal beliefs.Attitude has also been regarded as a predictor of intention 50 .Tuan and Pham 68 described attitude as an evaluation of an action, specifically on whether the outcomes of the action would influence (increase or reduce) the propensity of executing the action.In the case of entrepreneurship, Liñán and Chen 96 described attitude towards entrepreneurship as personal evaluation of whether one can become an entrepreneur.Meanwhile, Anderson 97 identified attitude towards entrepreneurship as an important determinant of entrepreneurial intention.
Studies have highlighted the translation of favourable evaluation of becoming an entrepreneur into entrepreneurial intention 78 .In the context of social entrepreneurship, attitudes towards entrepreneurship are an assessment of action 98 .In other words, an individual with positive attitude towards entrepreneurship is more likely to be involved in social entrepreneurship 99 .Similarly, students are highly likely to have a desire to become social entrepreneurs if they have a high level of desire to engage in social entrepreneurial behaviour 68 .When individuals with favourable attitude towards entrepreneurship receive support from the society, they are likely to possess the emotional strength to strengthen their social entrepreneurial intention 19 .With that, the current study formulated the following hypothesis for testing: H6 ATE positively influences SEI.

Subjective norms (SUN) and social entrepreneurial intention (SEI)
As part of normative beliefs in TPB, the construct of subjective norms reflects the perceived social pressure and motivation to execute a certain behaviour based on the evaluation of the significant others 100 .Apart from establishing one's perception of oneself, personal beliefs, and expected results, it can influence the one's intention towards a particular behaviour 101 .When an individual receives the approval and support from the significant others (e.g., family, friends, or society) to perform a certain activity, the individual is likely to form the intention of performing the activity.
Social entrepreneurs rely heavily on social network connections to pursue their social mission, which leads to the possibility that their background and the people around them may play a significant role in their thoughts and behaviours 102 .Yang et al. 103 found higher tendency of forming social entrepreneurial intention among potential social entrepreneurs within the collectivist cultural context in China than those in the United States.Tiwari et al. 99 observed similar outcomes on the positive influence of subjective norms on social entrepreneurial intention among students within the collectivist context in India.In another study, Mamun et al. 104 identified subjective norms as a significant determinant of students' entrepreneurial intention.These studies presented notable findings that suggest the strong correlation between subjective norms and social entrepreneurial intention within the Chinese cultural context.Thus, the current study tested the following hypothesis based on a sample of Chinese students: H7 SUN positively influences SEI.

Perceived behavioural control (PBC) and social entrepreneurial intention (SEI)
Ajzen 48 described perceived behavioural control as the extent of perceived ease or difficulty in executing a certain behaviour.It describes one's belief of whether one has the capacity to perform a specific activity 105 .Studies have used perceived behavioural control as a predictor of intention and actual behaviour [106][107][108] .With that, the current study viewed perceived behavioural control as the extent of one's perceived ease or difficulty in starting a business and becoming an entrepreneur.
Studies on entrepreneurship have demonstrated the significance of perceived behavioural control.For instance, Joensuu-Salo et al. 109 positive found strong correlation between entrepreneurial ability and perceived behavioural control and the influence of gender on the relationship between entrepreneurial ability and perceived behavioural control.Several prior studies showed the formation of perceived behavioural control prior to entrepreneurial intention 110,111 .On a similar note, Tiwari et al. 112 highlighted perceived behavioural control as an essential factor that can positively influence social entrepreneurial intention.However, a recent study by Barba-Sánchez et al. 113 suggests that the positive impact of PBC on entrepreneurial intentions is completely overshadowed by attitudes towards entrepreneurial behaviour, contrary to most views.Nevertheless, the study continues to argue that PBC can directly and positively influence SEI in a social entrepreneurship perspective.Therefore, the following hypothesis was proposed for testing in the current study: H8 PBC positively influences SEI.

Mediating effects of ATE
The previous section discussed the positive influence of RTP, SEF, and NFA on ATE and the positive influence of ATE on SEI.Therefore, the current study postulated the potential mediating effects of ATE on the relationships of RTP, SEF, and NFA with SEI.RTP is one of the important dimensions in entrepreneurial activity due to the high level of uncertainty 57 .Any entrepreneur is prepared to take risks before deciding to start a business 55 .Although social entrepreneurs are more risk-averse than general entrepreneur 114 , Hossain 115 still found that potential social entrepreneurs would have a higher propensity to take risks.Moreover, a higher risk-taking mentality positively fosters positive attitudes towards entrepreneurship and future perceptions of starting a social venture among university students 61 .Chipeta and Surujlal 116 had found that both RTP and ATE can positively influence SEI after testing with a multiple linear regression equation.Tu et al. 61  www.nature.com/scientificreports/graduate students to take risks, the higher their ATE and SEI, and that the relationship between ATE and SEI was also positively significant.However, none of studies directly verified the mediating role of ATE.Generally speaking, the stronger an entrepreneur's SEF is, the more entrepreneurial he/she will be and the more likely he/she will have the intention to start a business 117 .A high level of SEF creates a positive attitude towards entrepreneurship 65 .SEF helps an individual to generate social entrepreneurial intentions by showing him/her the feasibility of creating a social venture 118 .The stronger the SEF on social entrepreneurship, the more confident entrepreneurs are in recognising the opportunities for social change and the more likely they are to commercialise their social enterprise ideas 119 .In a more recent studies, the direct and significant influence of SEF on SEI has been verified 120,121 .In studies of entrepreneurship, ATE has been found to be an intermediate variable between SEF and entrepreneurial intentions 122 .It has also been suggested that individuals' behavioural attitudes and entrepreneurial attitudes can mediate SEF and SEI 68,105 .In conjunction with the aforementioned literature review, there is reason to believe that there is also a mediating role for ATE in SEF and SEI.
NFA is associated with the possibility of engaging in entrepreneurial activities, demonstrating an individual's ambition to achieve, acquire skills and achieve challenging goals 123 .Entrepreneurs always have a higher NFA than other professions and it is a driving force for their entrepreneurial intentions 124 .Enhancing students' NFA can motivate students to choose entrepreneurship as a career 76 .NFA can also be described as a desire to do better and be more adventurous 125 .From these aspirations to becoming entrepreneurial ideas, a good entrepreneurial attitude is needed to maintain creativity, innovation and problem-solving skills 125 .Barton et al. 126 state that motivated by the desire to achieve, students develop the will to form a social enterprise to fulfil the desire for self-fulfilment and autonomy.Combined with the above literature, NFA has the potential to motivate students to SEI by generating positive ATE.
Thus, the current study tested the following hypotheses: H9a-c ATE mediates the relationship between RTP, SEF and NFI on SEI.
All association hypothesized above are presented in Fig. 1

Methodology Sample selection and data collection
The current study targeted current students or graduates of one private university and four public universities in Southern China.They include one university of Project 985, two Double First-Class universities but not in Project of 985, one First tier university and one Second tier university.The use of self-administered questionnaire survey and cross-sectional data was deemed adequate for the current study to examine factors that influence SEI.Moreover, the self-administered approach has been widely used to explore entrepreneurial intention 104,120 .We released this survey in June 2022 and concluded respondent recruitment and questionnaire collection in July 2022.First, we collected a sample larger than 100 in each university where possible, as Reinartz et al. 127 proposed a minimum threshold of 100 samples for structural equation modelling via partial least squares (PLS-SEM).
Respondents from each university were sampled via the convenience sampling techniques.The universities of these respondents were located in South China, but they were from almost all over the country.G*Power (G*Power version 3.1.9.7) was used in this study to determine the minimum sample size required for the current study (effect size of 0.15, alpha of 0.05, power of 0.95 and 8 latent variables) and the results were calculated to indicate a minimum sample size of 160 128 .Also, referring to the suggestion of Gefen et al. 129 , the sample size should ideally be 10 times larger than the total number of items in the questionnaire.Based on the 48 items of the questionnaire involved in this study, the recommended sample size is at least 480 respondents.To ensure that a sufficient sample size was available for analysis after screening out non-useful responses, this study conducted a cross-sectional study to collect data in a specific population through an online questionnaire, resulting in 805 questionnaires.After data screening to remove responses that were under the age of 18 and incomplete responses to the informed consent form, only 684 questionnaires were used for this study.

Instrument
The questionnaire comprised two main components.The first component gathered information on respondents' demographics, including gender, age, education level, and household income.The second section discusses the items used to evaluate all variables in this study.RTP was measured using items provided by Mahmood et al. 78 , Mamun et al. 104 , and Wiramihardja et al. 79 .SEF items were adapted from Mahmood et al. 78 .Items for measuring NFA were taken from Mahmood et al. 78 and Wiramihardja et al. 79 .The questions used to assess PVS were taken from Han et al. 130 and Kim et al. 85 .ORG items were adopted from Lim et al. 91 and Wiramihardja et al. 79 , whereas ATE items were adapted from Mahmood et al. 78 , Mamun et al. 104 , and Wiramihardja et al. 79 .Mahmood et al. 78 and Mamun et al. 104 provided the items used to assess SUN.Mamun et al. 104 described the items used to assess PBC.Finally, we used SEI elements from Hockerts 131 and Mahmood et al. 78 .The prior study validated these items, assuring the questionnaire's validity and removing the requirement for a pre-test in this investigation.Participants were asked to rate their comments on a five-point Likert scale, from 'strongly disagree' (1) to 'strongly agree' (5).The supplementary material includes all of the items utilized in this study (Table S1.Survey Instrument).

Common method bias (CMB)
Common method bias refers to the perceived artificial covariation between the predictor and calibrator variables due to the same data source, measurement setting, as well as the context and characteristics of the items.Systematic error occurs under certain circumstances, such as the propensity of respondents to provide consistent or similar responses across measures due to the structure, wordings, or proximity of items and the similarity of time, medium, or place of data collection 132 .In order to minimise CMB, all items were meticulously constructed, and all respondents were properly briefed on the anonymity and confidentiality of their data and responses and the absence of specific (correct or incorrect) answers to the questions.Harman's 133 single-factor test was also conducted, which revealed negligible effect of CMB (34.259% < threshold of 50%).Table 1 presents the variance inflation factor (VIF) of each construct-all recorded values did not exceed 3.3 134 .In other words, there was no multi-collinearity issue.

Multivariate normality
The online Web Power tool (https:// webpo wer.psych stat.org/ models/ kurto sis/) was used in this study to validate the multivariate normality of the acquired data despite the absence of such criterion for the analysis (PLS).Based on the obtained results, Mardia's multivariate skewness and kurtosis p-values did not exceed 0.05, suggesting non-normality.

Validity and reliability
Referring to Table 3, PVS recorded the highest mean value.On the other hand, SUN recorded the lowest mean value and the highest standard deviation, which indicated the substantial variation of subjective norms among the respondents.Adding to that, the internal consistency of the instrument was determined based on the values of Cronbach's alpha coefficient, composite reliability, and Dijkstra-Henseler's rho.The obtained values exceeded 0.7, which confirmed the reliability of the instrument.The values of average variation extraction (AVE) and factor loadings were also determined.As shown in Table 3, the obtained values of AVE exceeded 0.5, suggesting good convergent validity.Fornell-Larcker criterion, heterotrait-monotrait (HTMT) ratio, and cross-loadings were used in this study to measure the discriminant validity of the reflective measurement model items.Based on the results of Fornell-Larcker criterion in Table 4, the diagonal exceeded the recorded correlation coefficients in the corresponding columns, suggesting good discriminant validity.Besides that, recorded values for heterotrait-monotrait (HTMT) ratio were below 0.9, which established good discriminant validity.Referring to Table 5, the external loadings of items on the corresponding constructs exceeded the cross-loadings of items on the other constructs 136 , which confirmed good discriminant validity of the items.www.nature.com/scientificreports/
Thirdly, the obtained results revealed the direct influence of RTP (β-value = 0.051, p-value < 0.001), SEF (β-value = 0.042, p-value < 0.001), and NFA (β-value = 0.032, p-value < 0.01) on SEI.Referring to the recommendation by Hair et al. 137 on the testing of mediating effects, the current study considered the variance accounted Adding to that, the current study examined the predictive relevance of the model based on the coefficient of determination (R 2 ) and effect size (f 2 ).Based on the general rule of thumb for R 2 by Hair et al. 138 , the predictive power of ATE (R 2 = 0.311) and SEI (R 2 = 0.393) was between medium and weak.Meanwhile, the effect sizes for most of the constructs were between small (0.02) and medium (0.15), except for PBC (f 2 < 0.02).Besides that, the results confirmed SUN as the strongest endogenous predictor of SEI.Overall, the model demonstrated good predictive relevance.www.nature.com/scientificreports/

Multi-group analysis
This study assessed the measurement invariance of composite models (MICOM) for the compositional invariance assessment.In the permutation test, the recorded p-values of all constructs for the case of university subject (i.e., social science versus natural science) did not exceed 0.05, suggesting the absence of compositional invariance.However, all p-values of constructs for the case of gender in this permutation test exceeded 0.05, implying the presence of compositional invariance.With that, this study proceeded to compare the standardised path coefficients by gender through MGA in PLS.Referring to the results in Table 7, gender did not lead to the outcome of significant differences for most of the pathways (p-value > 0.05).Interestingly, a significant difference between male and female respondents was observed in the relationship between NFA and ATE (p-value < 0.01), which suggested that the formation of SEI in men is more significantly affected by NFA than women.

Discussion
The significance of social entrepreneurship has gained growing research interest as a solution to the emerging social and environmental issues 139 .With respect to TPB, the current study empirically examined the influence of attitude towards entrepreneurship, subjective norms, and perceived behavioural control on social entrepreneurial intention, as well as the mediating effects of attitude towards entrepreneurship on the relationships of risk-taking propensity, self-efficacy, and need for achievement with social entrepreneurial intention.This study intended to extend TPB with two additional factors, namely perceived values on sustainability and opportunity recognition competency.Chinese university students and graduates were targeted in this study.This study obtained adequate empirical evidence on the significant and positive influence of risk-taking propensity, self-efficacy, and need for achievement on attitude towards entrepreneurship.Firstly, the obtained results in this study confirmed the significance of risk-taking propensity of Chinese students and graduates as a determinant of their attitude towards entrepreneurship.Previous studies have come to inconsistent conclusions about the relationship between RTP and ATE.For example, Ahmad and Malik 140 proposed that individual RTP significantly influences attitudes towards entrepreneurship intention.Shukla and Kumar 141 validated the mediating role of ATE in the relationship between RTP and entrepreneurial intention, while also emphasizing the positive impact of RTP on ATE.However, Mahmood et al. 78 did not test for a significant effect of RTP on ATE in a sample of Malaysian millennials.Indeed, culture has an influence on the relationship between risk propensity and behaviour.Under the influence of Chinese culture, university students choose more difficult challenges when their risk-taking decisions increase 142 .Therefore, when the propensity for risk-taking increases, Chinese university students' attitudes toward entrepreneurship also increase.Secondly, self-efficacy has been shown to positively influence entrepreneurial attitudes, consistent with the finding of Bouarir et al. 143 and Sekerbayeva et al. 144 .SEF has the ability to shape the entrepreneurial mindset of university students 144 .In social entrepreneurship, students www.nature.com/scientificreports/with higher self-efficacy show more enthusiasm 68 .The study demonstrated that individuals who believe in their own abilities are more likely to have positive attitudes toward entrepreneurship.Thirdly, the study verified that need for achievement is a positive predictor of attitude towards entrepreneurship.Our study is consistent with the results obtained by Dzomonda and Neneh 145 as well as Bağış et al. 146 .The NFA influences individuals' perceptions of their entrepreneurial careers 145 .It motivates students to aspire to improve their abilities to pursue their goals 77 .The higher the NFA, the more students want to set challenging goals for themselves and solve difficult problems 79 .The results show that students with this characteristic have a more positive attitude towards entrepreneurship.Furthermore, based on the results of mean and standard deviation, the participating Chinese students and graduates in this study demonstrated medium levels of risk-taking propensity, self-efficacy, and need for achievement.In other words, these students and graduates are not afraid of or proactive in taking risks and have neither positive nor negative attitude towards their ability to start a business and the need to gain a sense of achievement from it.This study also obtained adequate empirical evidence on the significant and positive influence of perceived values on sustainability, opportunity recognition competency, attitude towards entrepreneurship, subjective norms, and perceived behavioural control on social entrepreneurial intention.Firstly, individuals who are high perceived values on sustainability, meaning concerned about sustainable production and consumption, as well as engage in sustainable practices tend to be more concerned about the environmental implications of their behaviour 147 .They demonstrate higher propensity to make decisions that benefit or do not negatively influence the environment 148 .Consequently, they exhibit high level of social entrepreneurial intention.Secondly, we confirmed that the finding of Hoong et al. 94 about the positive relationship between ORG and SEI are correct.The ability to identify opportunities is crucial because the first step in trying to solve social problems is to identify social needs 31 .Research has demonstrated that individuals who are good at identifying potential opportunities and are keen to learn more about a product or service have higher social entrepreneurial intentions.Limited opportunity recognition abilities hinder individuals' engagement in social entrepreneurship 93 .Moreover, PVS and ORG are proven influencing factors for SEI, suggesting that individuals who form social entrepreneurial intentions will first possess pro-environmental motivation and the ability to contribute to the occurrence of social entrepreneurship.
Prior studies that explored students' entrepreneurial intention typically explored the significance of opportunity recognition competency, attitude towards entrepreneurship, subjective norms, and perceived behavioural control as antecedent variables 91,97,104,110 .These constructs clearly demonstrated their significance influence of enhancing social entrepreneurial intention among the participating university students and graduates in this study.Firstly, our study, along with those of Yamini et al. 19 and Handayani et al. 149 , confirmed the positive effect of ATE on SEI.Entrepreneurial attitude is an assessment of social entrepreneurial behaviour 98 .The positive attitude towards social entrepreneurship plays a crucial role in the formation of interest in becoming a social entrepreneur 149 .The finding is not only for general entrepreneurship, but our study also proves that it can be applied in the context of social entrepreneurship.Secondly, the findings show that SUN is a positive influencing factor for SEI.While the same result was obtained in the study of Tiwari et al. 105 as well as Durac and Moga 150 , Handayani et al. 149 did not find any effect of SUN on SEI.Potential social entrepreneurs in China, living in a culture with a strong collectivist concept, readily succumb to the influence of those around them to develop SEI 103 .The study, along with Tiwari et al. 105 , coincidentally finds that SUN was the strongest of the five influences on SEI, which demonstrates the importance of the role of norms in Chinese culture.The results also suggest that pressure and encouragement from society, family, and friends regarding entrepreneurship can make students think about the possibility of starting a social enterprise.Thirdly, the study also verified the positive effect of PBC on SEI.This finding is consistent with the results reported by Durac nd Moga 150 as well as Handayani et al. 149 .PBC has been considered the strongest predictor of entrepreneurial intentions and SEI in past studies 105 .Liñán and Chen 96 even directly defined PBC as the ease of becoming an entrepreneur.This point shows a strong correlation between students' PBC and their becoming social entrepreneurs, which is also identical to the results of our study.The findings suggest that individuals with strong SEI will perceive themselves as capable of managing a good business, having resources available and having the opportunity to start a business.Basically, the level of SEI is higher when an individual has the goal and confidence of becoming an entrepreneur, receives support from the significant others to pursue social entrepreneurship, and has access to the required resources for social entrepreneurship.The results imply that the TPB is also applicable in the study of SEI, and again demonstrate that TPB can be widely used in the construction of intentional models.
Besides that, the current study empirically demonstrated the significant and positive influence of risk-taking propensity, self-efficacy, and need for achievement on social entrepreneurial intention and the partial mediating effects of attitude towards entrepreneurship on the above relationships.Of these three mediating relationships, only the mediating role of ATE between SEF and SEI has been directly demonstrated 105 .Our study reaffirms this relationship and points to a partially mediating role of ATE.Individuals with stronger SEFs are prone to have positive effect on ATEs, which in turn generate stronger SEI.SEFs can also directly influence SEI because the stronger the SEF, the more confident individuals are in finding social needs and the more willing they are to commercialize them 119 .However, there are no existing studies that directly describe the mediating role of ATE in the relationship between RTP, NFA, and SEI.Our study fills this gap and confirms partial mediating roles of ATE in them.First, the more motivated students were to take risks, the less they feared entrepreneurship and the more pronounced their positive attitudes and tendencies toward social entrepreneurship 61 .Second, NFA as an aspiration that wants to be transformed into the idea of creating a social enterprise requires the help of a good entrepreneurial attitude 125,126 .Based on the obtained results, therefore, students and graduates with high risk-taking propensity, self-efficacy, and need for achievement will possess social entrepreneurial intention, and will form positive attitude towards entrepreneurship prior to the formation of the intention to engage in social entrepreneurship.
Vol:.( 1234567890 www.nature.com/scientificreports/Last but not least, the current study found significant difference between men and women in their need to gain a sense of fulfilment from entrepreneurship.Gender differences in entrepreneurship have been a hot topic in the field of entrepreneurship 151 .Vodă and Florea 152 have found gender differences in the effect of need for achievement on entrepreneurial intentions, with men in particular being more likely to entertain the idea of entrepreneurship due to the pursuit of achievement.However, some studies have also concluded that female university students have greater achievement motivation and achievement needs than male students 153,154 .Our results demonstrate differences between males and females in the relationship between NFA and ATE, and males show a greater effect; however, this difference does not exist in the effect of ATE on SEI.The results suggest that men display higher interest to achieve fame, fortune, and social status than women, which can be achieved through entrepreneurship.The pursue for social status often leads men to be more enthusiastic about entrepreneurship.However, there is no longer a difference between men and women when it comes to transforming entrepreneurial attitudes into social entrepreneurial intentions.This implies that gender plays a minor role in the formation of more specific and strong social entrepreneurial intentions.The bias in our results compared to previous studies may be due to the fact that the study focused on university students and graduates in southern China, where men are more concerned about being successful in their careers due to traditional beliefs, and therefore the influence of the need for achievement is more pronounced in the male population.Surprisingly, this study did not find any differences in the other influential factors among the participating students and graduates with different university subjects (i.e., social science versus natural science).

Implications Theoretical implications
This study contributes to the existing literature on social entrepreneurship in some ways.The first and most important contribution is the inclusion of the study of perceived values on sustainability and opportunity recognition competency in the field of social entrepreneurial intentions.The present study attempts to empirically demonstrate how perceived values on sustainability and opportunity recognition competency encourage individuals to generate ideas for social entrepreneurship through our proposed model.We hope that the results of this study will reveal how pro-environmental values and abilities that are beneficial to entrepreneurship contribute to understanding the formation of social entrepreneurial intentions.
Based on the basic framework of the Theory of Planned Behavior, this study further expands the antecedents of social entrepreneurial intention based on the existing literature.First, this study extends the application of TPB in the field of social entrepreneurial intention research.We attempt to identify additional influences at the individual level and construct and validate a modified model to explain the formation of social entrepreneurial intentions, providing new insights for social entrepreneurship research.Second, the study further contributes to the growing literature focusing on the role of individual psychological dispositions of men and women in their entrepreneurial preparation activities.

Practical implications
In addition to theoretical insights, this study has practical implications for the development and promotion of social entrepreneurial intentions among university students and the general population.First, government and universities should focus on risk-taking propensity, self-efficacy and need for achievement.research has demonstrated the predictive effects of these three factors on attitudes towards entrepreneurship.Policymakers should provide more safeguards against entrepreneurial risk to increase the confidence of potential entrepreneurs in dealing with risk, making them more risk-averse and increasing their risk propensity.Universities can help university students increase their entrepreneurial confidence and boost their self-confidence by conducting some courses and implementing some programs.At the same time, the cultivation of the need for achievement requires not only the development of appropriate strategies by universities, but actually the desire to pursue achievement needs to be conveyed before the university stage and even during the process of personal growth.These will effectively contribute to enhance the entrepreneurial attitude of individuals to become positive.
Second, perceived values on sustainability and opportunity recognition competency are important validations that distinguish this study from other TPB-based studies on social entrepreneurial intentions and may be worthier of attention by potential entrepreneurs and policy makers.Both universities and governments should make efforts in promoting sustainability values.The government needs to develop policies targeted at enhancing sustainability and help individuals develop pro-environmental values.Universities, on the other hand, should do a better job of promoting relevant policies to convey to students the idea of protecting the environment and helping sustainability.In addition to values-based training, universities should provide courses, lectures, and hands-on activities to enhance entrepreneurial skills (especially opportunity recognition) to increase students' motivation to participate in social entrepreneurship practices.These measures and actions will have a positive impact on the intention of individuals to engage in social entrepreneurship activities.
Third, this study also re-emphasizes the positive and significant effects of attitude towards entrepreneurship, subjective norm and perceived behavioural control on social entrepreneurial intentions University administrators and policy makers must pay attention to entrepreneurial attitudes because it is the most direct factor that makes It is important for university administrators and policy makers to pay attention to entrepreneurial attitudes because it is the most direct factor in generating social entrepreneurial intentions.They should develop strategies and measures to help students and the general population develop the right entrepreneurial attitudes and mindsets.These correct mindsets and attitudes encourage individuals to be innovative and expect results.Universities and governments should also provide a supportive environment for students to develop social entrepreneurship ideas and related knowledge and skills.These can contribute to the enhancement of students' subjective norms.In addition, perceived behavioural control needs to be addressed.This can be done by conducting training sessions www.nature.com/scientificreports/and programs to enhance individual confidence in entrepreneurship.Universities can also arrange social entrepreneurship mentors for students to help them have the opportunity to increase their entrepreneurial contacts and resources for their social entrepreneurial activities.

Conclusions
As a growing research area in entrepreneurship, social entrepreneurship plays a significant role and yields substantial benefits.Firstly, new businesses increase employment opportunities, promote economic development, and develop individual employability and entrepreneurial skills 155 .Secondly, these new businesses effectively deal with social inequalities, promote social efficiency, and promote sustainable use of resources 156 .Considering that, the development of social entrepreneurship in developing countries is deemed essential, especially with the prevalence of social issues like poverty and inequality 29 .
Exploring factors that influence social entrepreneurial intention provides valuable insights on why individuals decide to pursue social entrepreneurship.Addressing that, the current study demonstrated the significance of perceived values on sustainability, opportunity recognition competency, attitude towards entrepreneurship (as predicted by risk-taking propensity, self-efficacy, and need for achievement), subjective norms, and perceived behavioural control in developing social entrepreneurial intention.The findings are aligned with the TPB framework.Moreover, this study empirically proved the partial mediating effects of attitude towards entrepreneurship on the relationships of taking propensity, self-efficacy, and need for achievement with social entrepreneurial intention.Furthermore, this study found that gender can lead to the differences in the formation of NFA-ATE pathways-men are more likely to have favourable attitude towards entrepreneurship than women due to their pursuit of achievement.
The current study encountered several limitations.Firstly, this study conveniently sampled 684 university students and graduates from five selected universities in Southern China only for an online survey.The convenient sampling strategy is generally easier to implement, but the selected sample may not evenly distribute.The limited sampling area (Southern China) and the inclusion of university graduates in this study resulted in a sample that was not fully representative of the target population (Chinese university students).Therefore, it is recommended for future research to consider a larger random sample across different regions in order to obtain a more representative sample of Chinese university students.Secondly, this study expected that university subjects contribute significant differences in the influence of certain determinants of social entrepreneurial intention.However, the obtained results proved otherwise.The courses taken or the values developed by students in different subjects may not exhibit any significant influence on their social entrepreneurial intention.Nonetheless, this study noted the possibility that the sample selection or insufficient subject differentiation may contribute to different outcomes.Therefore, it is recommended for future research to have a more explicit comparison on whether there are differences in social entrepreneurial intention among students from different disciplines (e.g., business and engineering).Thirdly, the research methods we used have limitations.the PLS-SEM may not be sufficient to face the complexity of social sciences.Future scholars can use more appropriate data methods to validate our model.Finally, this study suggests that the difference between males and females in the effect of achievement needs on entrepreneurial attitudes stems from the influence of Chinese culture, but this has not been confirmed.Future research is expected to focus on whether culture can explain the gender-induced differences.
